I tested a mothership vs 4 corrupters and the mothership won with full health and sheild. This is impossible. The mothership is not cloaked, everything else near it is. You need to fix this. Also, you need to add mutalisks, broodlords, ultralisks, carriers, etc. Basically every awesome unit (except for the Terran ones) are not in it. Also, I want to be able to pit two collosi against a bunch of zerglings, but you only let us make 4. It is very boring to have 2 collosi obliterate such a small number of zerglings. Also, I pit two small groups against each other, and I think it is frustrating to simulate it over and over. You should make it so that it automatically simulates about 10-15 times (at least) and averages the results so we dont have to click over and over. Finally, you need to have a terrain editor so we can put units on high ground, or have a wall. Come to think of it, you should also A. add buildings, and B. Let us place units where we want. However, for those who need it quick, I suppose there could be a basic setting.
Why did I give it 2 stars? A. It has potential. B. It has all of the terran units, and banelings
